Am I right or wrong about partner and boundaries?

When I was with my ex he always to me had some really strong boundaries as in not letting anyone mess with him. When we got together and I was let into his world and throughout our relationships span there was never anyone that didn't treat me well. He didn't have to be in the room or anywhere close. I could move around in not always the safest places and again even if he was not around it was as is I felt his presence then working through some friend of his in mission.

Moving forward with my last partner when he let me in his world I got myself a mix experience with people who were not letting me in, but focusing on the established group they already had and may have had some already decided prejudice against me, to him doing family stuff that all it took was someone decided I was to be excluded and he did not make a word of protest. It has been situations when someone as soon as he left the room would say uncalled, nasty things to me, etc. Not everyone was like that, some nice (thank God). I have always felt as if I have been on my own with him.

If I was to compare my first ex with this other one I have come to the conclusion that the reason nobody ever messed with me before is because they had too much fear of my first ex, how he would react. There was this one time I got scared myself as I think he took it too far after learning about something. There was someone we didn't know too well who said/did something to me, but I expressed my boundary, thoughts, and to me it was over then and there, I had taken cared of it. I wouldn't tell him, but he was like this hawk and he said, did something too to that someone as I think he saw it as if you dare to mess with my girl I'll mess with you too, this ain't over til you have faced me too. As if he thought I let that someone get off the hook too easily. That sort of thing.

My Conclusion is that the people who messed with me with my later guy did so as they knew he wouldn't care, stand up, protect. No respect for him.
